Abstract:
Techniques are provided to allow global roaming between different devices in different networks, using different protocols. A system may contain one or more protocol dependent logic servers (PDLSs), in which each PDLS is associated with a particular network/network protocol. The networks may comprise one or more wired telecommunications networks, wireless communications networks, or Internet-based networks. When a first PDLS receives an incoming, protocol-dependent message comprising a first protocol from a first network intended for a user currently registered on another network, the first PDLS converts the protocol-dependent message into an incoming, protocol-independent message and forwards it to another network element, such as a core logic server (CLS). The CLS processes the incoming, protocol-independent message, generates an appropriate outgoing protocol-independent message and forwards this message to a second PDLS. The second PDLS converts the outgoing, protocol-independent message to an appropriate outgoing, protocol-dependent message and forwards it to a second network operating using a second protocol.
